📏 HiLetgo 2pcs 0.56 inch Digital Voltmeter Ammeter - DC 100V 10A Amp Voltage Current Meter Tester, 3 Bits Blue + Red Dual LED Display Panel with Connect Wires Review

The numbers are nice and bright (especially with the dedicated 30V supply which you really should do if you need to work below 4V). Unfortunately, the two separate gauges show 1.32A and 1.28A in both, for a measured load of 1.00A. That's about as little as I can adjust the trim. It sucks. I haven't tested much above 2A to see if the offset "increases" or if it's just a 300mA DC offset (pretty sure it'll increase by 30% so with a real 5A load 1.5A fail). Update and I tested at 3A (actual) and…

I planned to use this to measure the input voltage and current of a 24V DC motor. The input signal comes from a 24 VDC power supply with speed control. I measured voltage and current with separate meters before connecting these meters. I've never seen an initial surge of more than 3 amps when idling less than 1 amp with no load. and never feed more than 12 VDC into the motor. When I hooked up these gauges, the voltage reading was very accurate. The current was very high, then smoke came out of…

The first block in my separate 24-28V supply burned out immediately I switched on the second 5V block and it seemed to work correctly, but the current accuracy was about 20% lower. The voltage accuracy is not acceptable out of the box, but at least you can calibrate the voltage with the regulator on the back. I increased the supply voltage, and at about 22V the meter went off and lit up. This may be ok with low independent supply voltage of 5-12V, but not useful for my 24V application UPDATE…

Have both. They arrived in static safe packaging but I'm a little disappointed in the lack of wiring instructions because they have more woman than the voltmeter display I'm replacing. My previous one only had 2 wires to connect, they have 2 sets of wires, 1 set of 3 (red, black and yellow) and the 2nd set I was expecting (regular red and black). The way you combine it with red and black makes your finger stand out really well. After returning to my wife I bought it and finally found the…
